INTRODUCTION

Casinos and other establishments may have video gaming terminals that may include game machines, online gaming systems (that enable users to play games using computer devices, whether desktop computers, laptops, mobile devices, tablet computers or smart phones), computer programs for use on a computer device (including desktop computer, laptops, mobile devices, tablet computers or smart phones), or gaming consoles that are connectable to a display such as a television or computer screen.

Video gaming terminals may be configured to enable users to play games with a touch interface. Example games may be a slot machine game, which may involve a reel of symbols that may move by pulling a lever to activate the reel of symbols. A user may win a prize based on the symbols displayed on the reel. In addition to slot machine games, video gaming machines may be configured to enable users to play a variety of different types of games, which may involve displaying one or more game components on a display screen. To interact with a game component of the game, the user may have to press a button that is part of the machine hardware, or the user may have to touch a button displayed on a display screen.

A casino or other establishment has finite space, so it can operate only a certain number of video gaming terminals. The size of a video gaming terminal may be limited by its hardware, which may limit the number of game components, buttons, or interfaces that can be displayed on a display screen. This hardware limitation may also limit the amount of and types of physical interactions that a user may engage in with the machine to play the game. For convenience to the player, a casino or another establishment may want the player to have different experiences while playing at the same video gaming terminal. However, since a video gaming terminal and its associated hardware have finite size, there may be a limit on the number of buttons or physical elements present on the gaming terminal.

There is a need to immerse the user in their gaming experience while at the same video gaming terminal, and there is a further need to make more efficient use of the physical limitations of the hardware of the video gaming terminal. Therefore it is necessary to innovate by launching new and engaging electronic game machines with improved hardware where the player can interact with the interactive game using their eye gaze.

The embodiments described herein pervasively and integrally relate to machines, and their uses; and the embodiments described herein have no meaning or practical applicability outside their use with computer hardware, machines, a various hardware components.

As described herein, EGM 10 may be configured to provide an interactive game environment. The interactive game environment may be a 2D or 3D interactive game environment. The interactive game environment may include a plurality of visible and/or invisible game components or game symbols based on the game data. The invisible game components may be masked or blocked by the visible game components. The game data may relate to a primary interactive game or a bonus interactive game, or both. For example, the interactive game environment may comprise a 3D reel space that may have an active primary game matrix of a primary subset of game components. The bonus subset of game components may be different from the primary subset of game components. The player may view a viewing area of the interactive game environment, which may be a subset of the interactive game environment, on the display device 12, 14. The interactive game environment or the viewing area may be dynamically updated based on the eye gaze, eye gesture, or movement of the player in real-time or near real-time. The update to the interactive game environment or the viewing area may be a graphical animation effect displayed on the display device 12, 14. In some embodiments, the graphical animation effect may represent a visual update to the visible game component to reveal an invisible game component. The update to the interactive game environment or the viewing area may be triggered based on the eye gaze, eye gesture, or movement of the player. For example, the update may be triggered by looking at a particular part of the viewing area for a pre-determined period of time, or looking at different parts of the viewing area in a pre-determined sequence, or widening or narrowing the eyes. The interactive game environment may be updated dynamically and revealed by dynamic triggers from game content of the primary interactive game in response to electronic data signals collected and processed by EGM 10.

For an interactive game environment, the EGM 10 may include a display device 12, 14 with auto stereoscopic 3D functionality. The EGM 10 may include a touch screen display for receiving touch input data to define player interaction commands. The EGM 10 may also include at least one data capture camera device, for example, to further receive player input to define player interaction commands. The EGM 10 may also include several effects and frame lights. The 3D enhancements may be an interactive game environment for additional game symbols.

EGM 10 may include an output device such as one or more speakers. The speakers may be located in various locations on the EGM 10 such as in a lower portion or upper portion. The EGM 10 may have a chair or seat portion and the speakers may be included in the seat portion to create a surround sound effect for the player. The seat portion may allow for easy upper body and head movement during play. Functions may be controllable via an on screen game menu. The EGM 10 is configurable to provide full control over all built-in functionality (lights, frame lights, sounds, and so on).

EGM 10 may also include a plurality of effects lights and frame lights. The lights may be synchronized with enhancements of the game. The EGM 10 may be configured to control color and brightness of lights. Additional custom animations (color cycle, blinking, etc.) may also be configured by EGM 10. The custom animations may be triggered by certain gaming events.

FIG. 2A is a block diagram of hardware components of EGM 10 according to some embodiments. EGM 10 is shown linked to the casino's host system 41 via network infrastructure. These hardware components are particularly configured to provide at least one interactive game. These hardware components may be configured to provide at least one primary interactive game, at least one bonus interactive game, or both.

A communications board 42 may contain circuitry for coupling the EGM 10 to network. Communications board 42 may include a network interface allowing EGM 10 to communicate with other components, to access and connect to network resources, to serve an application, to access other applications, and to perform other computing applications by connecting to a network (or multiple networks) capable of carrying data including the Internet, Ethernet, plain old telephone service (POTS) line, public switch telephone network (PSTN), integrated services digital network (ISDN), digital subscriber line (DSL), coaxial cable, fiber optics, satellite, mobile, wireless (e.g. WMAX), SS7 signaling network, fixed line, local area network, wide area network, and others, including any combination of these. EGM 10 may communicate over a network using a suitable protocol, such as the G2S protocols.

Communications board 42 communicates, transmits and receives data using a wireless transmitter, or it may be wired to a network, such as a local area network running throughout the casino floor, for example. Communications board 42 may set up a communication link with a master controller and may buffer data between the network and game controller board 44. Communications board 42 may also communicate with a network server, such as in accordance with the G2S standard, for exchanging information to carry out embodiments described herein.

Game controller board 44 includes memory and a processor for carrying out program instructions stored in the memory and for providing the information requested by the network. Game controller board 44 executes game routines using game data stores in a data store accessible to the game controller board 44, and cooperates with graphics processor 54 and display controller 52 to provide games with enhanced interactive game components.

EGM 10 may include at least one data capture camera device for implementing the gaming enhancements, in accordance with some embodiments. The EGM 10 may include the at least one data capture camera device, one or more sensors (e.g. optical sensor), or other hardware device configured to capture and collect in real-time or near real-time data relating to the eye gaze, eye gesture, or movement of the player, or any combination thereof.

In some embodiments, the at least one data capture camera device may be used for eye gaze tracking, eye gesture tracking, movement tracking, and movement recognition. The at least one data capture camera device may collect data defining x, y and z coordinates representing eye gaze, eye gestures, and movement of the player.

In some examples, a game component may be illustrated as a 3D enhancement coming towards the player. Another game component may be illustrated as a 3D enhancement moving away from the player. The player's head position may be used as a reference for the at least one data capture camera device during a 3D enhancement. A player sitting directly in front of display 12, 14 may see a different view than a player moving aside. The at least one data capture camera device may also be used to detect occupancy of the EGM 10 or detect movement proximate to the EGM 10. The at least one data capture camera device and/or a sensor (e.g. an optical sensor) may also be configured to detect and track the position(s) of a player's eyes or more precisely, pupils, relative to the screen of the EGM 10.

The at least one data capture camera device may also be used to collect data defining player eye movement, eye gestures, body gestures, head movement, or other body movement. Players may move their eyes, their bodies or portions of their bodies to interact with the interactive game. The at least one data capture camera device may collect data defining player eye movement, eye gestures, body gestures, head movement, or other body movement. The game controller 44 may process and transform the data into data defining game interactions (e.g. selecting game components, focusing game components, magnifying game components, movement for game components), and update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect representative of the game interactions using the player eye gaze data, player eye gesture data, player movement data, or any combination thereof. For example, the player's eyes may be tracked by the at least one data capture camera device (or another hardware component of EGM 10), so when the player's eyes move left, right, up or down, one or more game components on display device 12, 14, may move in response to the player's eye movements. The player may have to avoid obstacles, or possibly catch or contact items to collect depending on the type of game. The player may focus on a particular location on the display device 12, 14 to cause a graphical animation effect to be displayed on display device 12, 14 representative of a visual update to a visible game component to reveal an invisible game component. These graphical animation effects within the game may be implemented based on the data derived from collected player eye gaze data, player eye gesture data, player movement data, or any combination thereof.

In some embodiments, the at least one data capture camera device may track a position of each eye of a player relative to display device 12, 14, as well as a direction of focus of the eyes and a point of focus on the display device 12, 14, in real-time or near real-time. The focus direction may be the direction at which the player's line of sight travels or extends from his or her eyes to display device 12, 14. The focus point may be referred to as a gaze point and the focus direction may sometimes be referred to as a gaze direction. In one example, the focus direction and focus point can be determined based on various eye tracking data such as position(s) of a player's eyes, a position of his or her head, position(s) and size(s) of the pupils, corneal reflection data, and/or size(s) of the irises. All of the above mentioned eye tracking or movement data, as well as the focus direction and focus point, may be examples of, and referred to as, player's eye movements or player movement data.

In some embodiments, the at least one data capture camera device may monitor the eye gaze, eye gesture, and/or movement of two or more people, who may be two or more players of the interactive game, to collect the player eye gaze data, player eye gesture data, and/or player movement data. The player eye gaze data, player eye gesture data, and/or player movement data may be used such that both players may be able to play the interactive game simultaneously. The player eye gaze data, player eye gesture data, and/or player movement data from one or more players of the interactive game may cause game controller 44 to trigger the control command to display controller 52 to display on display device 12, 14 a graphical animation effect to reveal one or more invisible game components. The interactive game may include aspects of both cooperative and competitive play.

A visible or invisible game component may be selected to move or manipulate with the player's eye movements. The gaming component may be selected by the player or by the game. For example, the game outcome or state may determine which symbol to select for enhancement.

As previously described, the at least one data capture camera device may track a position of a player's eyes relative to display device 12, 14, as well as a focus direction and a focus point on the display device 12, 14 of the player's eyes in real-time or near real-time. The focus direction can be the direction at which the player's line of sight travels or extends from his or her eyes to the display device 12, 14. The focus point may sometimes be referred to as a gaze point and the focus direction may sometimes be referred to as a gaze direction. In one example, the focus direction and focus point can be determined based on various eye tracking data such as position(s) of a player's eyes, a position of his or her head, position(s) and size(s) of the pupils, corneal reflection data, and/or size(s) of the irises. All of the above mentioned eye tracking or movement data, as well as the focus direction and focus point, may be instances of player movement data.

In addition, a focus point may extend to or encompass different visual fields visible to the player. For example, a foveal area may be a small area surrounding a fixation point on the display device 12, 14 directly connected by a (virtual) line of sight extending from the eyes of a player to the display screen. This foveal area in the player's vision may generally appear to be in sharp focus and may include one or more game components and the surrounding area. A focus point may include the foveal area immediately adjacent to the fixation point directly connected by the (virtual) line of sight extending from the player's eyes to the display screen.

The player eye gaze data and player eye gesture data may relate to the movement of the player's eyes. For example, the player's eyes may move or look to the left, which may trigger a corresponding movement of a game component within the game. The movement of the player's eyes may also trigger an updated view of the entire interactive game environment on the display device 12, 14 to reflect the orientation of the player in relation to the display device 12, 14. The player movement data may be associated with movement of the body of the player, such as the player's head, arms, legs, or other part of the player's body. As a further example, the player movement data may be associated with a gesture made by the player, such as a gesture by a hand or a finger. The EGM 10 may convert the focus data relative to display device 12, 14 to eye gaze data relative to the viewing area of the interactive game which may dynamically update.

In one embodiment of the invention, the EGM 10 may be configured to reveal, target, select, deselect, move, and/or rotate one or more visible and/or invisible game components based on player eye gaze data, player eye gesture data, and player movement data. For example, the EGM 10 may determine that a player has gazed at (e.g. the focus point has remained more or less constant) a previously unselected game component for three or more seconds, then the EGM 10 may select or highlight the game component, so the player may know that he or she may proceed to move or rotate the selected or highlighted game component. In another example, the EGM 10 may determine that after a player has selected a game component, the same player has moved his or her eyes to the right on a horizontal level for a predetermined length or period of time, then the EGM 10 may cause the selected game component to move to the right as well on a horizontal level. Similarly, the EGM 10 may determine that the player has moved his or her eyes down on a vertical level for a predetermined length or period of time, and then the EGM 10 may cause the selected game component to move to the bottom vertically.

Display controller 52 may control one or more of display device 12, 14 using graphics processor 54 to display a viewing area that may include one or more visible game components masking or blocking one or more invisible game components based on the game data of an interactive game.

Display controller 52 may, in response to detection of the control command from the game controller 44 based on the player eye gaze data, player eye gesture data, or player movement data, control display device 12, 14 using graphics processor 54. Display controller 52 may update the viewing area to trigger a graphical animation effect displayed on one or both of display device 12, 14 representative of a visual update to the visible game components to reveal the invisible game component in the viewing area, the visual update based on the player eye gaze data, player eye gesture data, or player movement data.

In some embodiments, the at least one data capture camera device and the display device 12, 14 may be calibrated. Calibration of the at least one data capture camera device and the display device may be desirable because the eyes of each player using the EGM 10 may be physically different, such as the shape and location of the player's eyes, and the capability for each player to see. Each player may also stand at a different position relative to the EGM 10.

The at least one data capture camera device may be calibrated by the game controller 44 by detecting the movement of the player's eyes. In some embodiments, the display controller 52 may control the display device 12, 14 to display one or more calibration symbols. There may be one calibration symbol that appears on the display device 12, 14 at one time, or more than one calibration symbol may appear on the display device 12, 14 at one time. The player may be prompted by text, noise, graphical animation effect, or any combination thereof, to direct their eye gaze to one or more of the calibration symbols. The at least one data capture camera device may monitor the eye gaze of the player looking at the one or more calibration symbols and a distance of the player's eyes relative to the EGM 10 to collect calibration data. Based on the eye gaze corresponding to the player looking at different calibration symbols, the at least one data capture camera device may record data associated with how the player's eyes rotate to look from one position on the display device 12, 14 to a second position on the display device 12, 14. The game controller 44 may calibrate the at least one data capture camera device based on the calibration data.

For example, as shown in FIG. 3, before the player 310 plays the interactive game, the EGM 10 may notify the player 310 that the at least one data capture camera device (not shown) and the display device 12, 14 may be calibrated. The display controller 52 may cause the display device 12, 14 to display one or more calibration symbols 330. In FIG. 3, nine calibration symbols 330 “A” through “I” are displayed, but the calibration symbols 330 may be any other symbols. For example, the calibration symbols 330 may be one or more game components related to the interactive game to be played. The calibration symbols 330 may be displayed on any portion of the display device 12, 14. The player 310 may be prompted to look at the calibration symbols in a certain order. The at least one data capture camera device may monitor the eye gaze 320 of the player 310 looking at the calibration symbols 330 and the distance of the player's eyes relative to the EGM 10 to collect the calibration data. When the at least one data capture camera device collects player eye gaze data in real-time, the game controller 44 may compare the player eye gaze data with the calibration data in real-time to determine the angle at which that the player's eyes are looking.

The display controller 52 may calibrate the display device 12, 14 using the graphics processor 54 based on the calibration data collected by the at least one data capture camera device. The at least one data capture camera device may monitor the eye gaze of the player to collect calibration data as described herein. The display controller 52 may calibrate the display device 12, 14 using the graphics processor 54 to display a certain resolution on the display device 12, 14.

In some embodiments, the game controller 44 may determine the location of the eye gaze relative to the viewing area based on the position of the player's eyes relative to the EGM 10 and an angle of the player's eyes. As shown in FIG. 4, the at least one data capture camera device 420 may monitor the position of the player's eyes 430 relative to EGM 10, and may also monitor the angle of the player's eyes 430 to collect display mapping data. The angle of the player's eyes may be determined based on the calibration of the at least one data capture camera device 420 described herein. The angle of the player's eyes may define the focus of the eye gaze, which may be a line of sight relative to the display device 12, 14. Based on the display mapping data, which may comprise the position of the player's eyes relative to the EGM 10 and an angle of the player's eyes or the line of sight relative, the game controller 44 may be configured to determine the direction and length of a virtual array 440 projecting from the player's eyes 430. Virtual array 440 may represent the eye gaze of the player 410. The game controller 44 may determine where the virtual array 440 intersects with the display device 12, 14. The intersection of virtual array 440 and display device 12, 14 may represent where the eye gaze of the player 410 is focused on the display device 12, 14. The display device 12, 14 may be controlled by display controller 52 to display the viewing area. The game controller 44 may identify coordinates on the display device 12, 14 corresponding to the player eye gaze data and may map the coordinates to the viewing area to determine the eye gaze of the player relative to the viewing area. EGM 10 may determine the location of the viewing area that the player 410 is looking at, which may be useful for EGM 10 to determine how the player 410 is interacting with the interactive game. The location of the viewing area that the player 410 is looking at may correspond to one or more invisible game components. In some embodiments, the eye gaze of the player may be expressed in 2D or 3D and may be mapped to a 2D or 3D viewing area, depending on whether the interactive game is a 2D interactive game or a 3D interactive game.

Peripheral devices/boards communicate with the game controller board 44 via a bus 46 using, for example, an RS-232 interface. Such peripherals may include a bill validator 47, a coin detector 48, a smart card reader or other type of credit card reader 49, and player control inputs 50 (such as buttons or a touch screen).

Player input or control device 50 may include the keypad, the buttons, touchscreen display, gesture tracking hardware, and data capture camera device as described herein. Other peripherals may be one or more cameras used for collecting player input data, or other player movement or gesture data that may be used to trigger player interaction commands. Display device 12, 14 may be a touch sensitive display device. Player control input device 50 may be integrated with display device 12, 14 to detect player interaction input at the display device 12, 14.

Game controller board 44 may also control one or more devices that produce the game output including audio and video output associated with a particular game that is presented to the user. For example, audio board 51 may convert coded signals into analog signals for driving speakers.

Game controller board 44 may be coupled to an electronic data store storing game data for one or more interactive games. The game data may be for a primary interactive game and/or a bonus interactive game. The game data may, for example, include a set of game instructions for each of the one or more interactive games. The electronic data store may reside in a data storage device, e.g., a hard disk drive, a solid state drive, or the like. Such a data storage device may be included in EGM 10, or may reside at host system 41. In some embodiments, the electronic data store storing game data may reside in the cloud.

Card reader 49 reads cards for player and credit information for cashless gaming. Card reader 49 may read a magnetic code on a conventional player tracking card, where the code uniquely identifies the player to a host system at the venue. The code is cross-referenced by host system 41 to any data related to the player, and such data may affect the games offered to the player by the gaming terminal. Card reader 49 may also include an optical reader and printer for reading and printing coded barcodes and other information on a paper ticket. A card may also include credentials that enable host system 41 to access one or more accounts associated with a user. The account may be debited based on wagers by a user and credited based on a win.

Graphics processor 54 may be configured to generate and render animation game enhancements based on game data as directed by game controller board 44. The game enhancements may involve an interactive game environment that may provide one or more visible and invisible game components and graphical animation effects. Graphics processor 54 may be a specialized electronic circuit designed for image processing (including 2D and 3D image processing in some examples) in order to manipulate and transform data stored in memory to accelerate the creation of images in a frame buffer for output to the display by way of display controller 52. Graphics processor 54 may redraw various game enhancements as they dynamically update. Graphics processor 54 may cooperate with game controller board 44 and display controller 52 to generate and render enhancements as described herein. Graphics processor 54 may generate an interactive game environment that may provide one or more visible and invisible game components, for example, a 3D reel space of a plurality of game components. The graphics processor 54 may generate graphical animation effects to represent a visual update to the visible game components to reveal the invisible game components in the viewing area, the visual update based on the player eye gaze data, player eye gesture data, player movement data, or any combination thereof.

Display controller 52 may require a high data transfer rate and may convert coded signals to pixel signals for the display. Display controller 52 and audio board 51 may be directly connected to parallel ports on the game controller board 44. The electronics on the various boards may be combined onto a single board. Display controller 52 may control output to one or more display device 12, 14 (e.g. an electronic touch sensitive display device). Display controller 52 may cooperate with graphics processor 54 to render animation enhancements on display device 12, 14.

Display controller 52 may be configured to interact with graphics processor 54 to control the display device 12, 14 to display a viewing area defining the interactive game environment including navigation to different views of the interactive game environment. Player control inputs 50 and the at least one data capture camera device may continuously detect player interaction commands to interact with interactive game environment. For example, the player may move a visible game component to a preferred position, select a visible game component, reveal an invisible game component, or manipulate the display of the visible and invisible game components.

In some embodiments, display controller 52 may control the display device 12, 14 using the graphics processor 54 to display the viewing area that may have one or more visible and/or invisible game components. In response to the detection of the control command based on the player eye gaze data, player eye gesture data, player movement data, or any combination thereof, display controller 52 may trigger a graphical animation effect to represent a visual update to the visible game components in the viewing area to reveal the invisible game components.

While playing an interactive game on the EGM 10, the eyes of a player may move suddenly without the player being conscious of the movement. The eyes of the player may demonstrate subconscious, quick, and short movements, even if the player is not actively controlling their eyes to move in this manner. These subconscious, quick, and short eye movements may affect the game controller's determination of the eye gaze of the player based on the player eye gaze data. Accurate processing of the player eye gaze data related to these subconscious, quick, and short eye movements may result in detecting the location of the eye gaze of the player representative of eye twitching or erratic eye movements not reflective of the player's intended eye gaze, and may be distracting to the player. It may be useful for the player eye gaze data to be filtered to not reflect these quick and short eye movements, for example, so the determination of the eye gaze of the player relative to the viewing area by the game controller reflects the intended eye gaze of the player. It may also be useful for the portion of the player eye gaze data representative of the subconscious, quick, and short eye movements to have less determinative effect on the determined location of the eye gaze of the player. In some embodiments, the game controller 44 may define a filter movement threshold, wherein the game controller, prior to determining a location of the eye gaze of the player relative to the viewing area using the player eye gaze data collected by the at least one data capture camera device and updating the rendering of the viewing area, determines that the player eye gaze meets the filter movement threshold. The at least one data capture camera device may collect player eye gaze data.

The game controller 44 may process the player eye gaze data to correspond with a location on the viewing area. The game controller 44 may determine where the player is looking at on the viewing area based on a certain number of previously recorded player eye gaze data, for example, by tracking the last ten eye gaze positions to average out where on the viewing area the player is looking. The game controller 44 may limit the amount of previously recorded player eye gaze data that is used to determine where on the viewing area the player is looking. The game controller 44 may filter out, or “smooth out”, player eye gaze data outside of the pre-determined filter movement threshold, which may represent sudden and subconscious eye movement. The game controller 44 may map the eye gaze of the player to the viewing area using at least a portion of the filtered player eye gaze data to determine the location of the viewing area at which the player is looking, in order to map the player's eye gaze to the viewing area.

As another example, the game controller 44 may delay in processing the player eye gaze data associated with subconscious, quick, and short eye movements, so the detected location of the eye gaze of the player does not represent twitching or sudden unconscious eye movements which may trigger animation effects causing an unpleasant user experience. Large eye motions may also be associated with more delay in processing and more smoothing. In some embodiments, the game controller may partition the player eye gaze data associated with large eye motions into data representative of shorter eye motions. The game controller 44 may analyze the player eye gaze data to determine which data is associated with subconscious eye movement or with conscious eye movement based on a filter movement threshold, a time threshold, movement threshold, or any combination thereof. Player eye gaze data associated with quick eye movements over a certain period of time may be determined by the game controller 44 to be subconscious eye movement. The game controller 44 may delay in processing this portion of data so the detected location of the eye gaze of the player may be stable and may not distract the player, or the game controller may filter out this data and not process it. Player eye gaze data associated with large eye movements over a certain period of time may be determined by the game controller to be the player losing focus or being distracted. The game controller 44 may similarly delay in processing this portion of data or not process this portion of data. In some embodiments, game controller 44 may filter out, or “smooth out” player eye gaze data, player eye gesture data, player movement data, or a combination thereof, that may exceed the filter movement threshold, in the manner described herein.

The locations where EGM 10 may be used may have a variety of lighting conditions. For example, EGM 10 may be used in a restaurant, a hotel lobby, an airport, and a casino. It may be brighter in some locations and darker in other locations, or the light quality may fluctuate from brightness to darkness. In some embodiments, EGM 10 may include an infrared light source that illuminates the player. The infrared light sources may not interfere with the eyes of the player. In some embodiments, the at least one data capture camera device may be an infrared data capture camera device. The infrared data capture camera device may collect player eye gaze data, player eye gesture data, and player movement data without being affected by the lighting conditions of the locations where EGM 10 may be used. In some embodiments, EGM 10 may have a plurality of light sources providing a plurality of spectra of light, and the at least one data capture camera device may be a plurality of data capture camera devices configured to detect a plurality of spectra of light, so the at least one data capture camera device may collect player eye gaze data, player eye gesture data, and player movement data without being affected by the lighting conditions of the locations where EGM 10 may be used.

A player that plays an interactive game using EGM 10 may be wearing glasses. The glasses of the player may cause refractions of the light that illuminates the player. This may affect the at least one data capture camera device while it monitors the eye gaze, eye gesture, and/or movement of the player. Glasses that comprise an infrared filter may also interfere with or affect the at least one data capture camera device while it monitors the eye gaze, eye gesture, and/or movement of the player. EGM 10 may recognize that the player may be wearing glasses. For example, as the interactive game commences, display controller 52 may display on display device 12, 14 using graphics processor 54 a question asking the player if he or she is wearing glasses. The player may provide input indicating whether he or she is wearing glasses, such as, but not limited to, with an audio command, touch command, or with the player's eye gaze. As other example, the game controller 44 may recognize, based on processing the player eye gaze data from the at least one data capture camera device, that the light illuminating the player may be refracted, and may determine that the player is wearing glasses. When EGM 10 recognizes that the player may be wearing glasses, the game controller 44 may perform additional and/or more stringent filtering functions as described herein to compromise for the player's use of glasses and to accommodate the refractions of the light that illuminates the player. For example, the filter movement threshold may be set to be higher for players who wear glasses.

In some embodiments, the game controller 44 may be configured to predict the location of the eye gaze of the player relative to the viewing area at a future time using the player eye gaze data to facilitate dynamic update to the rendering of the viewing area. For example, if the game controller 44 determines that a player is changing their gaze on a horizontal plane from the left to the right, the game controller 44 may predict that the player may look at a game component displayed on the right side of display device 12, 14. The ability for game controller 44 to predict the location of the eye gaze of the player at a future time may be useful to rule out inaccurate readings. For example, while a player plays a game, the at least one data capture camera device may incorrectly detect a button on the clothing of a player to be the player's eyes, and may collect incorrect player eye gaze data based on the button. Based on the location of the eye gaze predicted by game controller 44, the incorrect player eye gaze data may be ruled out by game controller 44, and may not be processed by game controller 44 to trigger a control command to update the viewing area with a graphical animation effect. As another example, by predicting the location of the eye gaze, the display controller 52 may adjust the resolution of the display device 12, 14 where the player is not expected to be looking. This may be useful because the EGM 10 may have limited processing power. Not all visible game components may require high resolution. Only the game components that the player is looking at may require high resolution. The ability for game controller 44 to predict the location of the eye gaze of the player may allow display controller 52 to reduce the resolution of visible game components that the player may not be looking at, which may increase the efficiency of the processing power of the EGM 10.

In some embodiments, EGM 10 may apply one or more predictive techniques to develop a plurality of predicted points of eye gaze, which, for example, may approximate and/or estimate where a player's gaze will travel next. These predictions may also be provided for use by graphics processor 54 and/or game controller board 44 in relation with smoothing out and/or accounting for removal of transient readings, undesirable artefacts and/or inadvertent gaze positions. In some embodiments, the predictions may also be used to improve the performance of EGM 10 in relation to gaze capture and/or processing thereof, by, for example, applying heuristic techniques to reduce the number of computations and/or capture frequency by relying on predictions to interpolate and/or extrapolate between gaze positions captured.

For example, when a player looks at a location of a viewing area in an interactive game, the EGM 10 may record where they were looking and what events are being displayed to the player (e.g., as first movements and/or gaze positions). When an event is triggered a second time, the player's gaze movements are recorded into a data storage system, but then compared to the first movements. A comparison may include, for example, comparing positions, velocities, start and end positions, accelerations, etc. as between various gaze movements.

For example, for each duration, a path and end location may be calculated, and a predicted pathway may be developed based on these locations and stored in a data storage.

As the event is triggered more times (e.g., more iterations occur), the data may be accumulated and a predictive pathing model can be built. Once the predictive pathing model is developed, when the event is triggered, the EGM 10 could reduce the frequency of the gaze system updates and use the recorded pathing and final location to be used to reduce the overall computing resources required, for example (e.g., performing various steps of interpolation, extrapolation using the predictive pathing model).

Accordingly, predictive pathing can also be used to reduce errors being produced by the gaze system. Gaze systems may utilize cameras and edge detection to determine where the player is looking, and many utilize use infra-red light to see the player's eye. If there are other infra-red light sources, for example, such sources may cause the gaze camera to be impacted and may reduce accuracy of the gaze detection. Accordingly, predictive pathing may be useful to reduce error in similar situations where there may otherwise be recorded errors and/or aberrations.

Further, predictions may not be limited only to a current player. For example, aggregate information from a large population of players may be aggregated together to refine the model for predictive pathing. The model may, for example, take into consideration the type of player, the type of interaction the player is having with the EGM 10, the characteristics of the player (e.g., height, gender, angle of incidence), among others.

In some embodiments, the predictive pathing model may also be utilized in the context of a game. For example, if the game includes aspects which may be selectively triggered based on various inputs, an input for triggering may include predicted pathways. In some embodiments, objects and/or layers may be modified and/or altered.

In some embodiments, the player may play an interactive game with EGM 10 in communication with a mobile device. Depending on the game data of the interactive game, the player may play the interactive game on EGM 10, on the mobile device, or on both. The player may play the interactive game using their eye gaze, eye gestures, movement, the interface of the mobile device, or any combination thereof. The player may play the interactive game using only the eye gaze of the player while the player holds on to the mobile device with one or more hands. The mobile device may, for example, be a computer, personal digital assistant, laptop, tablet, smart phone, media player, electronic reading device, data communication device, or a wearable device, such as Google™ Glass, virtual reality device, or any combination thereof.

The player may be able to play the interactive game while the mobile device is in communication with EGM 10. When connected to the EGM 10, the viewing area may be displayed on display device 12, 14 or on the screen of the mobile device, or both. The viewing area may have one or more visible game components and/or invisible game components. The at least one data capture camera device on the mobile device and/or the EGM 10 may collect player eye gaze data, player eye gesture data, or player movement data, which may be processed by a game controller 44 of EGM 10 to determine a location of the eye gaze of the player relative to the viewing area displayed on the mobile device. The game controller 44 may trigger a control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gaze data, player eye gesture data, or player movement data, and location of the invisible game component. In response to the control command from the game controller 44, the display controller 52 may control the display device 12, 14, the mobile device, or both, in real-time or near real-time using the graphics processor 54 to dynamically update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect displayed on the display device 12, 14, the mobile device, or both, representative of a visual update to the visible game components to reveal the invisible game component in the viewing area.

In some embodiments, the mobile device in communication with EGM 10 may be configured to be a display device that compliments display device 12, 14 when playing the interactive game. The player may interact with the interactive game through the interface of the mobile device, through the EGM 10, or any combination thereof. The interactive game environment, viewing area, and game components of the interactive game may be displayed on the mobile device, display device 12, 14, or any combination thereof.

In some embodiments, a terminal may be connected to one or more EGM 10 over a network. The terminal may serve as a registration terminal for setting up the communication between the mobile device and any EGM 10 connected to the network. Therefore, the player does not have to physically go to EGM 10 to set up the link and play the interactive game associated with EGM 10.

Host system 41 may store account data for players. EGM 10 may communicate with host system 41 to update such account data, for example, based on wins and losses. In an embodiment, host system 41 stores the aforementioned game data, and EGM 10 may retrieve such game data from host system 41 during operation.

In some embodiments, the electronics on the various boards described herein may be combined onto a single board. Similarly, in some embodiments, the electronics on the various controllers and processors described herein may be integrated. For example, the processor of game controller board 44 and graphics processor 54 may be a single integrated chip.

FIG. 5 is a flowchart of a method 500 implemented by EGM 10 using various components of EGM 10. For simplicity of illustration, method 500 will be described with reference to FIG. 2A and EGM 10 but it may be implement using gaming device 35, game server 40 or a combination thereof.

As shown, EGM 10 may include a card reader 34 to identify a monetary amount conveyed by a player to the electronic gaming machine.

EGM 10 may include at least one data storage device storing game data for at least one interactive game or at least one bonus interactive game, or both.

EGM 10 may include graphics processor 54 to generate an interactive game environment and define a viewing area as a subset of the interactive game environment. The viewing area may have one or more visible game components masking or blocking one or more invisible game components based on the game data.

EGM 10 may include display device 12, 14 to display via a user interface the viewing area.

EGM 10 may include display controller 52 to control rendering of the viewing area on the display device 12, 14 using the graphics processor 54.

EGM 10 may include at least one data capture camera device to continuously monitor eye gaze of a player to collect player eye gaze data.

EGM 10 may include a game controller 44 for determining a location of the eye gaze of the player relative to the viewing area using the player eye gaze data, the location corresponding to the invisible game component, and triggering a control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gaze data and the location.

In response to detection of the control command, the display controller 52 controls the display device 12, 14 in real-time or near real-time using the graphics processor 54 to dynamically update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect displayed on the display device 12, 14 representative of a visual update to the visible game components to reveal the invisible game components in the viewing area.

In response to an outcome of the interactive game, the card reader 34 updates the monetary amount.

At 502 (FIG. 5), the at least one data capture camera device and the display device 12, 14 may be calibrated by game controller 44 and display controller 52 as described herein.

At 504, the graphics processor 54 may generate the interactive game environment in accordance with the set of game rules using the game data and define a viewing area as a subset of the interactive game environment. The viewing area may have one or more visible game components masking or blocking one or more invisible game components.

At 506, display controller 52 may control the display device 12, 14 may display via a user interface the viewing area.

At 508, the at least one data capture camera device may continuously monitor the eye gaze, eye gesture, and/or movement to collect player eye gaze data, player eye gesture data, and/or player movement data.

At 510, the game controller 44 may determine a location of the eye gaze of the player relative to the viewing area as described herein using the player eye gaze data, player eye gesture data, and/or player movement data, the location corresponding to the invisible game component, and trigger a control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gaze data, player eye gesture data, and/or player movement data, and the location of the invisible game component.

At 512, display controller 52 may, in response to detection of the control command, control the display device 12, 14 using the graphics processor 54 to dynamically update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect displayed on the display device 12, 14 representative of a visual update to the visible game components to reveal the invisible game components in the viewing area.

At 514, display controller 52 may trigger a winning outcome of the game for provision of an award based on the interactions of the player and the game, which may be associated with the player eye gaze data, the player eye gesture data, the player movement data, and/or the revealed invisible game components. The card reader 34 may update the monetary amount.

In some embodiments, the EGM 10 may recognize potential players proximate to the EGM 10. As shown in FIG. 6, the at least one data capture camera device may continuously monitor an area proximate to the EGM 10 to collect proximity data. The game controller 44 may process the proximity data to detect if a person is proximate to the EGM 10. If a person is detected proximate to the EGM 10 then the display controller 52 controls the display device 12, 14 to display an advertisement. The ability for EGM 10 to recognize potential players proximate to the EGM 10 and commence active self-promotion is useful to gain a competitive advantage over other gaming machines. It may also be useful for welcoming and encouraging players to play the game and provide the player with a sense of astonishment. In contrast to a gaming machine that may interact with a player after the player has inserted a ticket, pressed a button, or touched a screen, EGM 10 actively starts the player's decision-making process to interact with EGM 10 sooner.

In some embodiments, the display controller 52 may render a gaze-sensitive user interface on the display device 12, 14, wherein the game controller 44 detects the location of the eye gaze of the player relative to the viewing area using the player eye gaze data, and triggers the control command to display controller 52 to dynamically update the rendering of the viewing area to provide a real-time or near real-time the graphical animation effect displayed on the display device 12, 14 representative of a visual update to the gaze-sensitive user interface. For example, display controller 52 may control display device 12, 14 to display a gaze-sensitive user interface as shown in FIG. 7A and FIG. 7B. The player may gaze at the one or more visible game components 710 at the top of the display device 12, 14, and the display controller 52 may cause a graphical animation effect to be displayed representative of reducing the size of or hiding an options menu 720 at the bottom of the display device 12, 14.

As shown in FIG. 7A, the options menu 720 may be small and out of the way. As the options menu 720 is being hidden, display controller 52 may cause another graphical animation effect to be displayed representative of enlarging the one or more visible game components 710 to use the portion of the display device 12, 14 vacated by the options menu 720. As another example, as illustrated in FIG. 7B, the player may gaze at the bottom of the display device 12, 14, which may cause the options menu 720 to be revealed and additional options may appear on screen. When the option menu 720 is revealed, the one or more visible game components 710 may reduce or shrink in size to accommodate the options menu 720. The player may gaze at a specific area of display device 12, 14, and additional information may be displayed on display device 12, 14. Even though the EGM 10 may have one or two display device 12, 14, a gaze-sensitive user interface may effectively increase the size of the display devices available to EGM 10. For example, as illustrated in FIGS. 7A and 7B, display device 12, 14 may display one or more visible game components 710 and an options menu 720 without requiring an increase in size of the display device 12, 14. The gaze-sensitive user interface may optimize the use of the limited space available on display device 12, 14. By monitoring the eye gaze of the player, EGM 10 may demonstrate context awareness of what the player is looking at. For example, the EGM 10 may detect when the player is distracted by detecting whether the eye gaze of the player is on the display device 12, 14.

EGM 10 may reward a player for maintaining their eye gaze on positive game aspects. For example, the at least one data capture display device may collect player eye gaze data that may indicate that the player is looking at a particular positive game component, such as, but not limited to, a positive game component representative of the rewarding of points, credits, prizes, or a winning line on a reel game. The player eye gaze data may also indicate that the player is looking at a particular positive game component that may be a revealed invisible game component. The display controller 52 may control the display device 12, 14 to display a graphical animation effect to enhance the positive game component with additional fanfare, for example, a special particle effect, fireworks, additional resolution and/or size of the positive game component, greater colour contrast and brightness, or lights and noises. In some embodiments, the graphical animation effect may correlate with the amount of time the player has maintained their eye gaze on the positive game component. The longer the player focuses their eye gaze on the positive game component, the more graphical animation effects may be displayed by display controller 52 on display device 12, 14 and/or the duration of the graphical animation effects may be extended.

The EGM 10 may include a display device 12, 14 with auto stereoscopic 3D functionality. In some embodiments, the player may interact with a game component presented on a display device 12, 14 with auto stereoscopic 3D functionality. The game component may appear to be hovering. The player may interact with the game component with the eye gaze of the player. For example, the focus of the eye gaze may cause the display controller 52 to control display device 12, 14 with auto stereoscopic 3D functionality to provide a graphical animation effect representative of rotating the game component. As another example, the focus of the eye gaze may cause the display controller 52 to control display device 12, 14 with auto stereoscopic 3D functionality to provide a graphical animation effect representative of revealing an invisible game component. The EGM 10 that may have a display device 12, 14 with auto stereoscopic 3D functionality may allow a player to interact with the interactive game without their hands. This may be useful to not distract from or spoil the 3D effect provided by the display device 12, 14 with auto stereoscopic 3D functionality. Where the display device is a stereoscopic display device, the graphics processor 54 may generate left and right eye images based on a selected three-dimensional intensity level, and the game controller 44 may trigger the control command to the display controller 52 to dynamically update the rendering of the left and right eye images based on the player eye gaze data.

Tracking the eye gaze, eye gesture, and movement of a player to reveal masked or blocked invisible game components may be implemented for a variety of interactive games and graphical animation effects. For example, the game may be a game with a reel space and game symbols. As another example, the game may be a game to focus eye gaze on a game component. The eye gaze of the player on display device 12, 14 may be implemented as a graphical animation effect to find and reveal a hidden or obscured game component. As yet another example, the game component manipulated by the player's eye gaze, eye gesture, and movement may be a virtual avatar. The virtual avatar may be navigated in the game using the player eye gaze data, player eye gesture data, player movement data, or any combination thereof, to avoid obstacles and collect rewards.

In some embodiments, the display controller 42 may cause display device 12, 14 to display one or more visible game components in front of one or more invisible game components. Based on the player eye gaze data, such as player eye gaze data that may represent maintaining the player's eye gaze on the one or more visible game components, the graphical animation effect displayed on display device 12, 14 may represent looking behind the visible game component masking or blocking the invisible game component to reveal the invisible game component. For example, the graphical animation effect may be such that the visible game component slides away from its location or pivots inwardly or outwardly to reveal the invisible game component behind the visible game component.

In some embodiments, the game controller 44 may process player eye gaze data to determine the location of the eye gaze of the player relative to the viewing area and may trigger a control command for the display controller 52 to reveal an invisible game component and select the revealed invisible game component for a primary interactive game or a bonus interactive game. The display controller 52 may cause display device 12, 14 to render an invisible game component behind a visible game component. The player may focus their eye gaze at the visible game component for a certain period of time. After a certain pre-defined period of time, the invisible game component may be revealed. The player may focus their eye gaze at the revealed invisible game component for a certain period of time. After a certain pre-defined period of time, the display controller 52 may display on display device 12, 14 using graphics processor 54 a graphical animation effect representative of the player selecting the revealed invisible game component. The selection may trigger an event related to the interactive game, such as, but not limited to, a prize award, a bonus game, advancement or progression in the interactive game, ending the game, or any combination thereof. In some embodiments, after the invisible game component has been revealed, the player may select the revealed invisible game component through display device 12, 14, which may be a touch-sensitive display device.

An embodiment of the player's ability to reveal invisible game components, where the player's eye gaze may be represented by EGM 10 to act as x-ray vision, and select the revealed invisible game components is illustrated in FIGS. 9 through 13. Player 900 may be playing an interactive game on EGM 10. The interactive game shown in FIGS. 9 through 13 is a reel game, but the interactive game may be any type of game. Display controller 52 may control display device 12, 14 to display viewing window 910 that may contain visible game components 940 a, 940 b, and 940 c. Depending on the game data of the interactive game, there may be more or less visible game components. The visible game components 940 a, 940 b, and/or 940 c may be masking or blocking one or more invisible game components. For example, in FIG. 9, the player 900 may be presented with a screen on display device 12, 14 to pick a prize, which may be represented by visible game components 940 a, 940 b, and/or 940 c. The prize may be a multiplier prize, which may multiply the bonus bet made by the player 900. The player may not know the details of the multiplier prize, as the details may be represented by an invisible game component. The at least one data capture camera device may monitor the eye gaze of player 900 to collect player eye gaze data. Game controller 44 may calculate the location of the player's eye gaze on the display device 12, 14 and map the player's eye gaze 930 to the viewing area. The player eye gaze data may correspond to the player 900 focusing their eye gaze on one or more of the visible game components 940 a, 940 b, or 940 c.

The eye gaze 930 may correspond to the location of the invisible game component. Game controller 44 may trigger a control command to display controller 52 to display on display device 12, 14 using graphics processor 54 a graphical animation effect representative of a visual update to the visible game component to reveal the invisible game component. As shown in FIG. 10, player 900 may focus their eye gaze 930 on visible game component 940 a to reveal the details of the multiplier prize. The at least one data capture camera device may collect player eye gaze data that indicates that the player 900 is focusing their eye gaze 930 on visible game component 940 a for a certain period of time. The focus of the player's eye gaze 930 may correspond to the location of the invisible game component. As shown in FIG. 11, the game controller 44 may send a control command to display controller 52 to display a graphical animation effect on display device 12, 14 to remove visible game component 940 a and reveal the invisible game component 950 a. In FIG. 11, the revealed invisible game component 950 a may be a “2×” multiplier bonus. The multiplier prize corresponding to the revealed invisible game component 950 a may be revealed but may not be selected. The player 900 may make a decision based on the revealed invisible game component 950 a.

For example, the player 900 may not believe that a “2×” multiplier prize is a desirable bonus prize. As shown in FIG. 12, the player 900 may focus their eye gaze 930 on another visible game component, such as visible game component 940 b. The game controller 44 may determine that player 900 is looking at visible game component 940 b for a certain period of time. This may cause game controller 44 to send a control command to display controller 52 to display a graphical animation effect on display device 12, 14 using graphics processor 54 representative of a visual update to a visible game component to reveal an invisible game component, such as invisible game component 950 b, a “3×” multiplier prize, as shown in FIG. 13. The multiplier prize corresponding to the revealed invisible game component 950 b may be revealed but may not be selected. After the player 900 has revealed the invisible game components, where EGM 10 represented the player's eye gaze 930 as x-ray vision, the player 900 may focus their eye gaze on a revealed invisible game component to select the revealed invisible game component. The selection of the “3×” multiplier prize may trigger an event related to the interactive game, such as multiplying the bonus bet of player 900 by three.

In some embodiments, the display controller 42 may cause display device 12, 14 to display one or more visible game components in front of one or more invisible game components. The graphical animation effect may represent seeing through or rendering transparent the visible game component masking or blocking the visible game component to reveal the invisible game component. For example, based on the eye gaze of the player that may be focused on a portion of the visible game component, the display controller 52 may cause an a graphical animation effect to be displayed on display device 12, 14 such that the portion of the visible game component that the player may be looking at may become translucent to a certain degree or transparent. This may reveal the invisible game component hidden behind the visible game component.

In some embodiments, one or more invisible game components may be located in one or more portions of a viewing area, according to the game data of the interactive game stored in the at least one data storage device. A player may look at one or more portions of display device 12, 14 to reveal the one or more invisible game components. The at least one data capture camera device may collect player eye gaze data based on the player's eye gaze. The game controller 44, processing the player eye gaze data, may determine that there may be movement of the eye gaze of the player from one location of the display device 12, 14 to another. The game controller 44 may map the eye gaze of the player to the viewing area. The location of the eye gaze of the player may correspond to one or more invisible game components that may be masked or blocked by one or more visible game components. The game controller 44 may send a control command to the display controller 52. In response to the control command, the display controller 52 may control display device 12, 14 in real-time or near real-time using graphics processor 54 to update the rendering of the viewing area with a graphical animation effect that may represent a visual update of the one or more visible game components to reveal the one or more invisible game components.

In some embodiments, the at least one data capture camera device of EGM 10 may continuously monitor an eye gesture of the player to collect player eye gesture data. Moreover, the at least one data capture camera device of EGM 10 may continuously monitor the player's movement, such as movement of the player's head, movement of the player's body, or gestures made by the player to collect player eye gaze data or player movement data. The game controller 44 may trigger the control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gesture data and/or player movement data using the graphical animation effect to update the one or more visible game components to reveal the one or more invisible game components in the viewing area. For example, the at least one data capture camera device may collect player eye gesture data representative of the player squinting or widening their eyes at a visible or invisible game component displayed on display device 12, 14. The game controller 44 may trigger a control command to display controller 52 to update the rendering the viewing area in real-time or in near real-time by displaying a graphical animation effect representative of revealing and magnifying the invisible game component. As another example, the at least one data capture camera device may collect player movement data representative of the player moving their hand in a certain direction towards a visible or invisible game component displayed on display device 12, 14. The game controller 44 may trigger a control command to display controller 52 to update the rendering the viewing area in real-time or in near real-time by displaying a graphical animation effect representative of revealing the invisible game component, and/or interacting with the visible or invisible game component.

In some embodiments, one or more invisible game components may be located in one or more portions of a viewing area, according to the game data of the interactive game stored in the at least one data storage device. A player may look at or gesture at one or more portions of display device 12, 14 to reveal the one or more invisible game components. The at least one data capture camera device may collect player eye gaze data, player eye gesture data, and/or player movement data. The game controller 44, processing the player eye gaze data, player eye gesture data, and/or player movement data, may detect the eye gaze, eye gestures, and/or movement of the player from one location of the display device 12, 14 to another. The game controller 44 may map the eye gaze, eye gestures, and/or movement of the player to the viewing area. The location of the eye gaze, the eye gesture, and/or movement of the player may correspond to one or more invisible game components that may be masked or blocked by one or more visible game components. The game controller 44 may send a control command to the display controller 52. In response to the control command, the display controller 52 may control display device 12, 14 in real-time or near real-time using graphics processor 54 to update the rendering of the viewing area with a graphical animation effect that may represent a visual update of the one or more visible game components to reveal the one or more invisible game components, based on the player eye gaze data, player eye gesture data, and/or player movement data.

In some embodiments, the interactive game may require skill from the player to complete. For example, the interactive game may require a player to complete a task within a finite amount of time. The amount of time remaining for the player to complete the task may be displayed on display device 12, 14 to increase pressure on the player. For example, the interactive game may be a skill-based maze bonus game. The player may control an avatar using the player's eye gaze to travel through a series of mazes. The player may cause the avatar to collect prizes. There may be a timer to indicate the amount of time the player may navigate the maze. The maze bonus game may include visible game components and/or invisible game components. The maze may include traps that may be visible or invisible. A visible game component may mask or block an invisible trap. The player may look at a portion of the display device 12, 14, which may be mapped to a location of the viewing area that may correspond to an invisible trap, to cause display controller 52 to display on display device 12, 14 a graphical animation effect representative of a visual update to the visible game component to reveal the invisible trap. The player may look at the traps with their gaze to deactivate the traps and allow the avatar to continue through the maze. Once the player has guided the avatar to the exit, the player may play a new stage of the maze based upon the amount of prizes collect, or the maze game may finish. The threshold for the amount of prizes needed to be collected may progressively increase based upon which bonus stage the player is at. The maze bonus game may be configured to have one or more levels of difficulty. The higher the difficulty, the less time the player may have to complete the maze challenge and the player may have to navigate through more traps in the maze.

In some embodiments, for another skill-based maze game, while the player leads an avatar through a maze using the eye gaze of the player, there may be special tiles that the display controller 52 may be configured to cause to appear on the display device 12, 14. The player may have a specified number of breakable tiles actions. While moving the avatar through the maze, the player may break any wall by locking their gaze on the wall. In some embodiments, a breakable tile action may be an invisible game component that may be revealed by the eye gaze of the player. This may be used to help the player to find the exit.

In some embodiments, based on the game data of the interactive game, display controller 52 may display using graphics processor 54 one or more opaque objects on display device 12, 14. To interact with the interactive game, the player may use their eye gaze as x-ray vision to see through the one or more visible game components, such as the one or more opaque objects, to see the invisible game components, such as hidden information. For example, the one or more opaque objects may be a safe. The invisible game component may be a graphical element with levers. Inside the safe may be one or more levers and/or a tumbler. Based on the player eye gaze data, the display controller 52 may display a graphical animation effect that may represent seeing through the safe or revealing the graphical element with levers and/or a tumbler. The player may interact with and manipulate the tumbler, such as turning the tumbler to the correct position and moving the lever and rotating in the opposite direct when the correct positions of the lever and/or tumbler have been reached. The game controller may recognize that the correct positions of the lever and/or tumbler have been reached, and display controller 52 may display a graphical animation effect representative of opening the safe, which may reveal a prize.

In some embodiments, based on the game data of the interactive game, display controller 52 may display using graphics processor 54 one or more series of switches on display device 12, 14. To interact with the interactive game, the player may use their eye gaze as x-ray vision to see through the visible game component, such as the series of switches, to reveal the invisible game component, which may be a graphical element of a series of circuits and switches. The hidden circuits may connect the switches. The switches may be associated with a prize or a series of list prizes. The player may focus their gaze on a switch to select the switch corresponding to the prize that the player wants to win.

In some embodiments, as shown in FIGS. 14 to 16, based on the game data of the interactive game, the graphics processor 54 may generate a fog effect within the viewing area 1410 that may mask or block the invisible game component. The display controller 52 may display on display device 12, 14 the viewing area 1410 that may have a fog effect, as shown in FIG. 14. Player 1400 may focus their eye gaze 1430 to one or more portions of the viewing area 1410. The at least one data capture camera device may monitor the eye gaze 1430 of the player 1400 and may collect player eye gaze data. The game controller 44 may calculate the location of the eye gaze of the player relative to the viewing area 1410 using the player eye gaze data. The location of the eye gaze may correspond to the invisible game component. In this example, as shown in FIG. 14, the invisible game component may be the tropical island background and prizes obscured by fog effect generated by graphics processor 54. Game controller 44 may trigger a control command to the display controller 52 to dynamically update the rendering of the viewing area 1410 based on the player eye gaze data and the location of the eye gaze. In response to the control command, the display controller 52 may control display device 12, 14 using graphics processor 54 to display a graphical animation effect to reveal the invisible game component. In this example, as shown in FIG. 14, the scene is covered in fog. The player may not be able to see through the fog. To see through the fog, the graphical animation effect may be a transparent circle 1420 displayed at a location corresponding to the eye gaze 1430 of the player 1400 that removes the effects of the generated fog effect and reveals the tropical island background.

As shown in FIG. 15, the player 1400 may interact with the interactive game based on their eye gaze. For example, the player 1400 may focus their eye gaze 1430. The at least one data capture camera device may collect this player eye gaze data. Game controller 44 may recognize that the player is focusing their eye gaze 1430. Display controller 52, in response to a control command from game controller 44, may display a graphical animation effect on display device 12, 14 representative of expanding the transparent circle 1420, so the player may reveal more invisible game components.

As shown in FIG. 15, the player 1400 may move their eye gaze 1430. The game controller 44 may process the player eye gaze data collected by the at least one data capture camera device to determine that the eye gaze 1430 of the player 1400 has moved to another location. This new location may correspond to another invisible game component. The graphical animation effect displayed by display controller 52 on display device 12, 14 may reveal this other invisible game component. In FIG. 15, the player 1400 has moved their eye gaze 1430. The corresponding graphical animation effect may be moving the transparent circle to reveal a prize that was obscured by the fog effect. As shown in FIG. 16, the prize 1440 may be revealed after the player 1400 focuses their eye gaze 1430 at the location of the prize 1440 for a specified amount of time.

In some embodiments, based on the game data of the interactive game, display controller 52 may display using graphics processor 54 one or more avatars on display device 12, 14. For example, one or more avatars may be a spy. One or more invisible game components may be a graphical element of one or more avatars carrying a hidden document. The hidden documents may be obscured by the spy avatar. The spy may be attempting to sneak out hidden documents. To interact with the interactive game, the player may use their eye gaze as x-ray vision to see through the visible game component, such as the avatars, to determine which avatar is the spy, and reveal the invisible game component, such as the hidden documents. The player may focus their gaze on the spy holding the hidden documents to select the spy, which may trigger an event related to the interactive game, such as winning a prize.

In some embodiments, one or more players may play in a shared game or a multi-player game. The shared game or multi-player may be a primary interactive game or a bonus interactive game. The EGM 10 of one player may be in communication with one or more other EGMs, for example, wireless communication. The at least one data storage device may store game data for a shared game or multi-player game that may be a primary multi-player interactive game and/or a bonus multi-player interactive game. For example, during the shared bonus game, each player may search the viewing area displayed on display device 12, 14 for one or more invisible game components masked or blocked by one or more visible game components. The at least one data capture camera device on each EGM may monitor the eye gaze of the players and collect eye gaze data for each player. The invisible game component may be a bonus game component of a set of bonus game components. The bonus game components may be displayed as symbols, which may be related to the shared game or multi-player game. The player may use their eye gaze, such as focusing their eye gaze on a portion of the display device 12, 14, corresponding to the location of an invisible game component, to reveal the invisible game component. The player may further use their eye gaze, such as focusing their eye gaze on the revealed invisible game component, to select the revealed invisible game component. Game controller 44 may detect when a player has selected a pre-defined subset of bonus game components, using the player eye gaze data, such as a player selecting a certain combination of bonus game components or the same bonus game components. The selection of the pre-defined subset of bonus game components may trigger a bonus prize reward. For example, the first player to select a matching set of bonus game components may win the bonus prize.

The player may not want to select a revealed invisible game component. The player may use their eye gaze or eye gesture, such as looking towards the edge of the display device 12, 14, or blinking, to reject a revealed first bonus game component. The game controller 44 may detect the eye gaze and/or eye gesture of the player representative of rejecting the revealed invisible game component, and may trigger the display controller 52 to display on the display device 12, 14 a second bonus game component. The game controller 44 of EGM 10 may also cause the game controller 44 of another EGM to cause the display controller of the other EGM to display on the display device of the other EGM the revealed first bonus game component. This may give the effect of a player “passing along” a rejected bonus game component to another player.

In some embodiments, while one or more players are playing a shared game or a multi-player game, the display controller 52 of an EGM for a player may control the display device of the EGM to display different layers, each layer corresponding to the viewing area of the other players. While a player looks at their display device, the player may see the other player's viewing areas hidden behind their viewing area. In some embodiments, the shared game may be a reel game. When the players spin the reels, the rendering of each player's viewing area may be updated and may be viewed by each player. A player may view their own reels on their display device, except where the player's eye gaze is focused on the display device. Instead, at the portion of the display device that a player is looking at, the viewing area of one or more other players may appear and any win with a combination of the one or more viewing areas may give a prize to the one or more players. This may encourage cooperative play between multiple players. In some embodiments, a player may press a button to view the viewing area of another player.

In some embodiments, the graphics processor 54 may generate an interactive game environment with a set of game rules using game data, such that there may be one or more invisible game components. The graphics processor 54 may define a viewing area as a subset of the interactive game environment, which may contain one or more invisible game components. The display controller 52 may control the display device 12, 14 in real-time or near real-time using the graphics processor 54 to update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect representative of rendering visible at least a portion of the invisible game components in the viewing area. This may allow more game components to be displayed on the display device 12, 14, which may have finite size. For example, EGM 10 may provide a privacy mode for the player. There may be a menu at the bottom of display device 12, 14 that may display the credits conveyed to EGM 10 by the player or the amount of credits won by the player. By default, the credits may be invisible, blurred out, or masked or blocked by a visible game component. When the player focuses their eye gaze on the user interface, the display controller 52 may control display device 12, 14 to reveal or display the amount of credits. The graphical animation effect to reveal or display the amount of credits may be, for example, to display the invisible credit amount, to put in focus the blurred out credit amount, or to remove the visible game component and reveal the invisible credit amount. This may allow the player to hide the amount of credits associated with the player or the amount of credits won by the player from nearby observers.

A player may play one or more games at EGM 10. The player may have the option of selecting an interactive game from a plurality of interactive games to be played at EGM 10 when the player initially conveys credits to EGM 10. However, not all game selector symbols may be displayed on display device 12, 14 because the display device 12, 14 may lack space. Another reason may be that one or more game selector symbols may be intentionally masked or blocked so the player may find and reveal it to play a hidden or bonus interactive game. The player may use their eye gaze to display a plurality of game selector symbols and to select and play a game from the plurality of games. The player may also use their eye gaze to find and reveal one or more invisible game selector symbols masked or blocked by one or more visible game components and to select and play the corresponding game. In some embodiments, EGM 10 may have a card reader to identify the monetary amount conveyed by the player to the EGM 10. The EGM 10 may have at least one data storage device that may store game data for one or more primary interactive games and/or bonus interactive games. The graphics processor 54 may generate an interactive game environment in accordance with a set of game rules using the game data and define a viewing area as a subset of the interactive game environment, the viewing area having one or more game selector symbols. The viewing area may also have one or more visible game components masking or blocking an invisible game selector symbol. EGM 10 may have display device 12, 14 to display via a user interface the viewing area. EGM 10 may have a display controller 52 to control rendering of the viewing area on the display device 12, 14 using the graphics processor 54. At least one data capture camera device may continuously monitor the eye gaze of a player to collect player eye gaze data.

A game controller 44 may determine a location of the eye gaze of the player relative to the viewing area using the player eye gaze data, the location corresponding to the invisible game selector symbol, and triggering a control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gaze data and the location of the player eye gaze. In response to the control command, the display controller 52 may control the display device 12, 14 in real-time or near real-time using the graphics processor 54 to dynamically update the rendering of the viewing area to provide a real-time or near real-time graphical animation effect displayed on the display device 12, 14 representative of a visual update corresponding to selecting one of the game selector symbols, or revealing and selecting the invisible game selector symbol, in the viewing area and displaying a selected interactive game for the selected game selector symbol, the visual update based on the player eye gaze data. For example, display controller 52 may control display device 12, 14 to display a plurality of game selector symbols configured in the shape of a carousel. Based on the eye gaze of the player, such as up, down, left, or right, the display controller 52 may control display device 12, 14 to display a rotating carousel of game selector symbols, which may reveal additional and hidden game selector symbols. The player may focus on a portion of the display device 12, 14 to reveal one or more invisible game selector symbols. Based on the eye gaze of the player, such as looking at or near the center of display device 12, 14, the rotating carousel of game selector symbols may slow down or stop at a game selector symbol corresponding to the player's preferred game. The player may also focus on one or more visible game components to reveal the invisible game selector symbol. In response to an outcome of the interactive game, the card reader may update the monetary amount. The player may focus on the game selector symbol to select and play the game. In some embodiments, the player may scroll through the plurality of game selector symbols or reveal invisible game selector symbols using their eye gaze, eye gestures, the movement of their head, the movement of their body, or a combination thereof.

A player may use their eye gaze to navigate through the interactive game environment, change the camera angle on a visible game component or a revealed invisible game component, and discover and reveal invisible game components in the interactive game environment that may not be in the viewing area. The EGM 10 may have a card reader to identify a monetary amount conveyed by a player to the EGM 10. The EGM 10 may have at least one data storage device to store game data for an interactive game. The graphics processor 54 may generate an interactive game environment in accordance with a set of game rules using the game data and define a viewing area as a first subset of the interactive game environment, the first subset of the interactive game environment having a first visible game component masking or blocking a first invisible game component. The display device 12, 14 may display via a user interface the viewing area. Display controller 52 may control rendering of the viewing area on the display device 12, 14 using the graphics processor 54. At least one data capture camera device may continuously monitor eye gaze of a player to collect player eye gaze data. The game controller 44 may determine a location of the eye gaze of the player relative to the viewing area using the player eye gaze data and triggering a control command to the display controller 52 to dynamically update the rendering of the viewing area based on the player eye gaze data.

In response to the control command, the display controller 52 controls the display device 12, 14 in real-time or near real-time using the graphics processor to dynamically update the rendering of the viewing area in real-time or near real-time to navigate to the second subset of the interactive game environment, the second subset of the interactive game environment having a second visible game component masking or blocking a second invisible game component, wherein the update comprises a graphical animation effect displayed on the display device representative of navigating to the second subset of the interactive game environment, the update based on the player eye gaze data. In response to an outcome of the interactive game, the card reader updates the monetary amount. A player may use their eye gaze, eye gestures, head movement, body movement, or any combination thereof to navigate through the interactive game environment, change the camera angle on a visible game component, and discover and reveal invisible game components in the interactive game environment that may not be in the viewing area.

For example, as illustrated in FIG. 17 and FIG. 18, the graphical animation effect displayed on the display device 12, 14 may represent a smooth sliding transition from the first subset of the interactive game environment to the second subset of the interactive game environment. Graphics processor 54 may generate interactive game environment 1710 in accordance with a set of game rules using the game data for one or more interactive games stored in at least one data storage device. Interactive game environment 1710 may include one or more game components, some of which may be visible, while others may be invisible. In FIG. 17 and FIG. 18, two game components 1750 a and 1750 c are visible, and game component 1750 b is invisible as it may be masked or blocked by a visible game component, but there may be more or less game components based on the game data of the one or more interactive games. Graphics processor 54 may define a viewing area 1740 as a first subset of the interactive game environment. In FIG. 17, the viewing area 1740 includes visible game component 1750 a and excludes invisible game component 1750 b. Display device 12, 14 may display viewing area 1740. Display controller 52 may control rendering of the viewing area on the display device 12, 14 using the graphics processor 54. Game controller 44 may process player eye gaze data collected from the at least one data capture camera device to determine that the eye gaze 1730 of the player 1720 may be focused on visible game component 1750 a.

As illustrated in FIG. 17, player 1720 may view visible game component 1750 a on display device 12, 14. Player 1720 may wish to navigate to another area of the interactive game environment 1710. For example, player 1720 may wish to discover visible game components that may mask or block invisible game components. Game controller 44 may determine that the location of the eye gaze of the player relative to the viewing area has changed. For example, the player 1720 may be looking at the top of display device 12, 14. Based on this change of location of the eye gaze 1730, game controller 44 may trigger a control command to the display controller 52 to dynamically update the rendering of the viewing area 1740. Display controller 52 may update the rendering of the viewing area 1740 in real-time or near real-time to navigate to the second subset of the interactive game environment 1710. A graphical animation effect, such as a sliding animation effect, may be used to transition from the viewing area 1740 comprising a first subset of the interactive game environment 1710 to the viewing area 1740 comprising a second subset of the interactive game environment. As shown in FIG. 18, the viewing area 1740 is a second subset of the interactive game environment 1710 that is different from the first subset of the interactive game environment 1710. The viewing area 1740 comprising the second subset of the interactive game environment 1710 contains invisible game component 1750 b. The invisible game component 1750 b may be masked or blocked by one or more visible game components. Since the viewing area 1740 is displayed on display device 12, 14, from the perspective of player 1720, the player's eye gaze has caused a transition from a first subset of the interactive game environment 1710 to a second subset of the interactive game environment 1710. The effect of the eye gaze of the player may be to navigate the interactive game environment 1710. For example, the player 1720 may be looking at visible game component 1750 a, and through navigation of the interactive game environment 1710, the player 1720 discovered a second subset of the interactive game environment. This may create the effect that the display device 12, 14 is an infinitely large screen, or a larger screen than it actually is. The player 1720 may focus their eye gaze 1730 on the visible game component masking or blocking invisible game component 1750 b, which may cause display controller 52 to display a graphical animation effect on display device 12, 14 representative of a visual update to the visible game component to reveal invisible game component 1750 b in the second subset of the interactive game environment. This may give the player a sense of discovery and satisfaction as part of an engaging gaming experience.

As another example, one or more game components 1750 may be within a viewing area 1740 and displayed on display device 12, 14 with a certain camera angle or view angle. The game controller 44 may process collected player eye gaze data and trigger a control command to display controller 52 to update the rendering of the viewing area 1740 in real-time or near real-time to display a graphical animation effect representative of changing the camera angle or view angle. From the perspective of player 1720, the graphical animation effect may appear to be a rotation of the one or more game components 1750 on display device 12, 14. As yet another example, the player, using their eye gaze, may reveal an invisible game component and may rotate the revealed invisible game component.
